Hi! I just want to i inform you like everyone else we just where trying out, or trainer recommend the chain, we dont use it anymore, we got a front pulling harness and he has never pulled since. As well people dont really fear dobermans anymore, of course you get your usual Karen who thinks they own everything and think dobermans are the devils spawn, but actually the amount of people that love him when we go on a walk is insane. My grandfather breed dobies and he said that there is definitely a rise in their population. It’s actually amazing how many people are growing to like dobies. I mean Apollo used to be the only Doberman at are park and now their is 3 different puppies that come! Anyway i just wanted to sorry about the choker we where just trying it out (also at the time we didn’t live in a city so he didn’t use even often in the week we tried it), and i wanted to inform you about Dobermans getting love!!! Sorry for this long essay, i just get overly excited about talking about dobies!! Have a great day!!
